Research on Soil Moisture and Nutrients in Different Steppe Ecosystems

This study was carried on about soil moisture and nutrients of meadow steppe, typical steppe and desert steppe ecosystems. The results showed that meadow steppes had the maximum soil moisture content, while the desert steppes had the minimum. This was because the three types of steppes had different soil types and physical characteristics, and these physical characteristics influenced soil moisture content to some extent. Compared with that in the meadow steppes and desert steppes, carbon and nitrogen content of soil of the typical steppes were the highest, and the differences in soil carbon and nitrogen among the three types of steppes were significant or obviously significant. They were due to the geographical environments, temperature and precipitation caused by a combination of factors.
